App Composer

I recently developed a little GUI for packing Mac App Store apps. The tool is free to use, and I've called it App Composer.

App Composer is a tool that lets you package Mac applications for the Mac App Store with little hassle. We plan on updating it to potentially support more features and platforms.

App Composer comes with a 'transform' function that signs and adds stuff like the icon, replaces the plist, adds a resource folder, etc. It comes with a 'package' function which packages the selected .app file into a signed .pkg file, and an 'install' function which simulates a Mac App Store developer install from the terminal.

This tool is primarily intended for people who use engines such as GameMaker, Unity, etc, since XCode does most of the things App Composer does for you.
